Topological String Amplitudes, Complete Intersection Calabi–Yau Spaces and Threshold Corrections
We present the most complete list of mirror pairs of Calabi–Yau complete intersections in toric ambient varieties and develop the methods to solve the topological string and to calculate higher genus amplitudes on these compact Calabi–Yau spaces. These symplectic invariants are used to remove redundancies in examples. The construction of the B–model propagators leads to compatibility conditions...
متن کاملMirror Symmetry, Mirror Map and Applications to Complete Intersection Calabi-Yau Spaces
We extend the discussion of mirror symmetry, Picard-Fuchs equations, instanton-corrected Yukawa couplings, and the topological one-loop partition function to the case of complete intersections with higher-dimensional moduli spaces. We will develop a new method of obtaining the instanton-corrected Yukawa couplings through a study of the solutions of the Picard-Fuchs equations. This leads to clos...
متن کاملRigid curves in complete intersection Calabi-Yau threefolds
Working over the complex numbers, we study curves lying in a complete intersection K3 surface contained in a (nodal) complete intersection Calabi-Yau threefold. Under certain generality assumptions, we show that the linear system of curves in the surface is a connected componend of the the Hilbert scheme of the threefold. In the case of genus one, we deduce the existence of infinitesimally rigi...
متن کاملString Theory on Calabi-yau Manifolds
These lectures are devoted to introducing some of the basic features of quantum geometry that have been emerging from compactified string theory over the last couple of years. The developments discussed include new geometric features of string theory which occur even at the classical level as well as those which require non-perturbative effects. These lecture notes are based on an evolving set ...
متن کاملPlanar diagrams and Calabi-Yau spaces
Large N geometric transitions and the Dijkgraaf-Vafa conjecture suggest a deep relationship between the sum over planar diagrams and Calabi-Yau threefolds. We explore this correspondence in details, explaining how to construct the Calabi-Yau for a large class of M matrix models, and how the geometry encodes the correlators. We engineer in particular two-matrix theories with potentials W (X,Y ) ...
